变精度粗糙模型的建立及其在加工过程知识约简中的应用

The Establishment of Variable Precision Rough Set (VPRS) Model and Its Application in Knowledge Reduction of Cutting Process

本文针对基于粗糙集的数据挖掘过程,引进了可变精度的粗糙集模型进行知识约简,并在变精度粗糙模型的建立基础上,研究了其实现算法,并对加工过程中刀具磨损的数据进行挖掘和知识约简。

Variable precision rough set （VPRS） model is introduced in knowledge reduction for data mining. Based on the VPRS model, the knowledge reduction algorithm is detailed and applied in discovering the rules of tool wearing in cutting processes.
